2017 Lexus IS Seat Room and Comfort: Pros

2016

For me, the front bucket seats in Lexus F Sport models provide a nearly ideal blend of comfort and support. Even when they don't lack lateral support, the seats in competitors don't fit my form as well.
Infiniti doesn't offer the Q50 2.0t in Sport form. The standard car's front seats provide little lateral support.
The instrument panel appears larger and more imposing in the Infiniti than in the Lexus. Still, I wish the view forward were a little more open in the latter. (The Cadillac ATS is better in this regard.) Lexus lowered the driving position compared to the previous IS to help the car feel sportier. I raised the seat some to compensate.
Adding all-wheel-drive to the Lexus IS (and a V6 engine with it, AWD isn't offered with the 2.0T engine) adds another issue, a large hump beneath the driver's right calf. Some drivers might find they have to adjust how they sit to avoid this hump.

With 241 horsepower and 258 pound-feet of torque, the new turbocharged 2.0-liter four-cylinder engine in the Lexus IS 200t has much more competitive specs than the 204-horsepower, 185-pound-foot 2.5-liter V6 it replaces, and more power than the 208-horsepower, 258-pound-foot Mercedes 2.0T in the Infiniti Q50. In reality, it feels about as quick as the Infiniti but short on grunt and thrills compared to the 2.0T engines in the Audi A4 and BMW 328i.
The new Lexus engine could be refined to a fault. Boost comes on so gradually there's no evident transition. Compared to competing turbo fours it's smoother and much quieter, with a high-frequency tone to the noise that penetrates the sound insulation. The BMW engine in particular sings a lower, louder song and sounds and feels more energetic.
The IS 200t's eight-speed automatic could deserve some of the blame. It shifts very smoothly from gear to gear, but doesn't react as quickly or as decisively as others. Whether owing to the programming of the engine or the transmission, my connection to the team felt less than direct or immediate. While I found the car quick enough--it's probably quicker than the Infiniti--I found few thrills through the go-pedal.
For performance-minded drivers, the 306-horsepower, 277-pound-foot 3.5-liter V6 in the IS 350 remains the way to go. It's a splendid engine even if it lacks the brute power of the boosted sixes in the Audi, BMW, Infiniti, and Mercedes.
